of Virginia, have invented certain new and useful 1m rovements in Boiler-Tube Cleaners and do hereby declare the following to be a full, clear, and exact description of the invention," such as will enable others skilled in the art tojwhich it appertains tomake and use the same;

My invention relates to the class ofboilertube cleaners, and more particularly to that class in which jets of steam are thrown onto the rear end of theboiler.

The special object of my invention is theproduction of a spraying device which will efi'ectually direct a jet of steam into eachand every tubein the boiler to clean the same; and, the said device consists of the construction hereinafter set forth.

clearly illustrate In the accom anying drawings I have if my improved device, and

a full and exact description thereof is contained in the annexed specification.

In the accompanying drawings, Figure 1 is a perspective view of a steam-boiler with my I improved device employed in connection therewith, the brick casing being broken away to more clearly show my device. Fig.

- 2 is a side elevation, partly in section, of

my device. Fig. 3 is a longitudinal section through the casing and showing the nozzle and handle in elevation. Fig. 4 is a longitudinal section through the nozzle; and Fig. 5 is a section on line 4 4, Fig. 4. i

In the several views like letters of reference designatesiinilar parts of my improved device.

A in the supply pipe, and B a branch pipe therefrom, the main pipe A being provided near the joint with the branch pipe B with a stop-cock a.

' and the branch pipe B being provided with a sto -cock I).

drawings designates the steam- 1s a cylindrical casing located in the wall of the fire-box at a point opposite the center of the. boiler, the end of said casing adjacent to the boiler being flush with the inside of the wall, while the other end of said casing is provided with an externally-threaded portion 0, projecting beyond the outer face of the wall.

-D is.a hollow casing provided with an an nular flange d and an internal-l threaded ori- Patented arch 12, 1907.

- fice d, adapted'to engagewithtlie threaded end a of the casin C andat the other end" with an orifice d fice d, but of,reduced d entering a stuffing-box (i formed in the casingD- d is an inlet-port in .the side of the casing C and in direct .communicationlwith the.

branch pipe B. j I.

lrectl in linelwith the ori-. ameteir', said orifice E is the s 'raying-nozzle and hollow cyhn rical body E, having a rounded end e, provided with a central .dischageopening 3, adapted to direct ajet of-ste am' upwardly, and a series of discharge-open ngs e e e respectivel in'the under face and the sides of said roun ed end e, said openings bewardflly cylin rical 'body E is provided with. an anmg adapted to direct jets of-steam downand outwardly. The other end of the nular flange E and a conical portion E pro vided with oblong openings E, and at its end" with an octagonal or squared. projection E having an internally-threaded orifice E,

F is a rod adapted to freely slide in the opening (1 in the casing D and is supported in a conical-shaped bearing portion G, avin a threadedc lindrical projection g, adapts to fit into't e stuflin -box (1 and forms the gland therefor. T e rod F is provided at one end with a threaded portion adapted'to fit into the threaded-opening E in the nozzle E and at its other endyvith a handle f. With this construction it is obvious that the nozzle E, through the medium of the rod F, may be either reciprocated or revolved in the casing O. I

- The operation of my improved device is as follows: When the parts are ina normal posi tion, as shown in Fi 3, and when the stop cocks a, and b have been opened, the steam from the su ply pipe A will be 7 forced through the ll: thence through the openings E into the nozzle E, from which it escapes through the. openings e, e, and a into the cylindrical casing 0, which, it is obvious, will result in a ranch pipe into the casing D,

circular spray which will only strike a limited steam may be thrown intoe'very tube not already subjected to the action of the steam.

Whenall ofthe tubes have been, cleansed, the. sto -co'ck b is turned off and the nozzle drawn ack to normal position.

What Iclaim, and desire to secure by Letters l'atent, is

1. In a boiler-flue cleaner, the combination with a, stationary tubular casing, havin a charge-aperture angularly disposed to the axis thereof, and an operating-rod directly and rigidly connected to said nozzle and extending beyond said casing for positively projecting, retracting and rotating said noz- .zle, substantially as described.

2. In a boiler-flue cleaner, the combination "with a stationary tubular casing, having a i ed discharge-aperture at its end, and pro with a steam-inlet, of a hollow nozzle located within said casing and having a part snugly fitting the same and apart adapted to be projected through said j discharge-aperture eyond the end of said casing, said roject-' ing part of said nozzle being roun ed and provided with a discharge-aperture at its end and with series of apertures extendinglongitudinally of said nozzle, all of said apertures in said nozzle being angularly disposed to the axis thereof, and an o erating-rod directly' and rigidly connecte to said nozzle and extending outside of said casing for positively projecting, retracting and rotating said nozzle, substantially'as described. 3. In a boiler-flue cleaner, thecombination with a stationary tubular casing, havin a discharge-aperture at its end, and provi ed with a steam-inlet adjacent to its rear end, of

a hollow nozzle located within said casing and having a part intermediate of its ends snugly fitt ng said casing, the forward portion of said nozzle being of less di'arnetei' than that of the interior of said casing and provided with discharge-apertures angularly dis- I posed to the axis thereof, said forward portion of said nozzle being adapted tobe'projected through said discharge-aperture in said casing, the rearward portion of said nozzle beoutside of saidcasing for positively projecting, retractin and rotating said nozzle, substantially as escribed.

4. In a boiler-flue cleaner, the combination with 'a stationary tubular casing, havin a discharge-aperture at its end, and provi ed with a steam-inlet adjacent to its rear end,'of a hollow nozzle located within said casing and havin snugly fittlng said casing, the forward portion of said nozzle being of less diameter than that of,the interior of said casing and provided with dischargeapertures angularly disposed to the axis thereof, said forward portion of said nozzle being adapted to be pro'ected through said discharge-aperture in sai casing,zand rearward portion ,of said nozzle being tapered'toward us end and provided with slits therein forming inlet-apertures, an operating-rod directly and rigidly connected to the rear end of said nozzle and projecting through the rear end of said casmg for positively projecting, retracting and a part intermediate of its ends rotating said nozzle and a gland at the end of said casing surrounding said rod to prevent the escape of steam and to guide said rod,

substantially. as described.
